To ell 'whom t muy concern:

. Be 'it known that We, @crave li'rranmn,

Y a subject ot theling of Belgium, and` resi- Apparatus for Spreading Pyrites in Alloast-k ing-Furnaces, of which the Afollowing specification.

'This vinvention relates to mechanical pokersv and more particularly Ato that class of mechanical pokers adapted for use 'raith a furuace'aclaptecl for the roasting` of-pyrites inthe manufacture ofsulturic acid.

The. object of this invention is to provide a mechanical poker which shall reduce the time necessari)Y for the tiring of a furnace of this` typeto wminimum. y c

A further object of the inv'enti n is to procluc'e device or7 the character described which shall combine utility, cheapness, and durability.

llith these and other objects in View, the

il'n'eution consists of the peculiar combination and constructiony of the various parts Aof a mechanical poker as hereinafter clescribed and more particularly set forth in the appencleclclaims.

Reterringto the drawings wherein similar 'referenceA characters indicate similar parts Wherever usecl, Figure l is a sicle elevation of the device. Fig. 2 is a rear ele- Yration of 'the device showing a section through the operating mechanism.

The device comprises a framework l, composed preferahly'of Lal-irons holtedtogether, and mounted upon' axles 2, carrying flanged wheels 3, adapted to Iride upon rails el. Two distinctA apparatuses are mounted on this framework, one of these apparatuses, A, serv` ing to introduce `the 4charge of pyrites into the furnaces While the other one B comprises the whole working mechanism of the mechanical potters. The first named apparatus j. composed of a pulley Wheel 6 provided .'th a holler; orsolicl rim having ltwo pro- .ing flanges 'T upon which a belt 8 is passthis belt being made of any suitable @nal and heiugguicletl by three iCl-lers l5, 1G and 1 7 oue'ot which ascertains `the tenlever Wl0.

ln the actuallyv employed furnaces it the Stoker vat. least 5 minutes to 'introduce die the upper stories into the furnace with the shovel-. about .lll-9 With the ald of the mechanism kilograms. just described the work will .he tiene in one minute. y i

The mechanism B' oi 1e frs is coniposeclof a Vertical framework Ql'adaptecl te pivot at 22 and upon vwhich a truss frame 23 1s adapted te rise and descend-,- this truss traine 23 supporting the two poliers la the electricV motor 25 or other source of motive power, Well as all the apparatuses used for reciproca ng he polters. l

The apparatus coing s cally arranged polrers Q4: `which, however, never Work together. ltlis a Well linen/*n es two symmetrifact that the temperature of these furnaces is a high one and that when apc/ker has Worked tlurmg a cert u i 1:,1t-becon1es hot -antl has a tendency to lionel; consequently,

,zaratus notices'y When the operator of the Vu. L a cert-ain flexion' during the Work, he Withdraws it at once and sets the other one ,going thus alloisfvinggI the lirst one to cool flown.

The operating in oiclerto cause a poker to outer the furnace, raises 'it at its frontpart hy means et tile lever 6; if the pyrites h ave to he pushed tack, he causes the h poker to trail on the hottoin oit the it on the eontr...fr is df. M4icefl pyrites toward him, he keeps the poker viii a raised position out of touch witlitlic pyi'ites and lets it: drop at 'the' end ot' the fur nace.

The stroke of the poker is equal to the length ,of the furnace; thc operator by-simply' maneuveringma hand lever causes it to advance orto move backward attwill at a speed which may reach meters per second; he may cause' the poker tomove the whole forward or backward stroke without any stop or through any part of said stroke. The poker obcysduring this movement in the same manner as the poker which is manipulated by the workers hands in Vthe ordinary furnaces. At the rear part of thetrus's part is a slot 2f( which allows the Worker to raise orto lower the vvpoker iii certain cases Which movement can be carried out by hand by rotating in one direction or the other the hand Wheel 28 positioned near the operator of the machine. The said slot .1.alsolservestorectify the direction ot' the pokerin case ai flexion should super-vene.

The motor is started and works continuously; it has keyed upon its armature a smooth friction pinion 20 made ot' raw hide or any other suitable material. Keyed upon a 4horizontal shaft 30 are two 'friction cones 31' adapted to be brought into contact with the smooth pinion; on the said shaft and onboth sides of the said 'triction cones are two cast iron drums 32 havf 'ing an inwardlycurved rim and upon which the cables di'iving the pokers are wound. The said drums are rotating loosely on the sha'ft 30 and are provided with ratchet teeth 33 corresponding to a coupling device sliding onto tlie shaft f3() through the nicdium of a'key secured to said shaft. When the apparatus is started the said coupling devices are not engaged with the claws oi the drumsarid the smooth pinion rotates l with .a certain clearance between the frietion cones.

When the operator desires to put into ac `tioii one of thepolfers, he engages first one of the drums 52 into the teeth of its coupling device; thereati'ter he exerts a pressui'e on `one of the ends of the shaft byv means of a lever'l in order to `bring one ol. the cones into rentar: with the pinion. The shaft St) at once starts rotating in one'directioii and lcauses thc poker to advance and when at any desired moment, the operator' wants to bring the poker back toward himself, all that required is to exert a pressure by means ot' the saine lever on the opposite end of the shaft i as to bring the other conc into contact i. ich the pinion of tho motor. ln order to weil luider stand thisyvorking` it must be borne in mind that as the, motor always rotates in the t saine direction` il one of the cones brought into contact with the pinion, the horizontal.

tshaft will rotate in one direction and if |tlie frictional engagement of this cone is stopped and the other cone engaged with the pinion, the shaft will rotate inthe other drums, it t'olltiuf's-that the pokers follow the direction of movement of the cables and thus are ada ptedto perform a rapid reciprocating movement. Any other mechanical system might bc used to actuate the poker's,
